Moorehead, Minn. (AP) — Authorities say preliminary autopsy results show seven people whose bodies were discovered inside a Minnesota home did not die from “any obvious trauma.” Police say all seven victims, including three minors, lived at the residence in south Moorhead.

The Ramsey County Medical Examiner’s Office in St. Paul conducted the autopsies but did not determine a cause of death. Police say blood samples from the victims have been sent to a lab for further examination. The victims were found just before 8 p.m. Saturday by family members conducting a welfare check. Moorhead is on the Minnesota border next to Fargo, North Dakota.

Moorhead Police have identified the deceased as members of the Hernandez-Pinto family. They are 37 year old  Belin Hernandez, 34 year old Marleny Pinto, 16 year old Breylin Hernandez, 7 year old Mike Hernandez, 5 year old Marbely Hernandez, 32 year old  Eldor Hernandez Castillo, and  19 year old Mariela Guzman Pinto.

Police said the seven relatives were living at the home at 4403 13th St. S. where their bodies were found.
